Chisquared Distribution Calculus Function

Description

This function calculates the chisquared distribution of two vectors of numbers.

Usage

chisquared_(x,y)

Arguments

x

Should be a vector.

y

Should be a vector.

Details

To calculate the chisquared distribution, the user should give two vectors of numbers. The result is a sum of the squares of k independent standard normal random variables. The chisquared distribution formule is the following:

Value

Numeric, the chisquared distribution of two vectors of numbers.

Note

A vector is created by c(), like c(1,2,3,4,5) creates a vector with the numbers: 1,2,3,4,5
